Salomon Kalou insists that Chelsea are still capable of completing a league and Champions League double this season.

Chelsea jumped into fourth position by beating Barclays Premier League leaders Manchester United 2-1 at Stamford Bridge on Tuesday night, but Carlo Ancelotti was quick to play down suggestions that the victory meant his side were back in the title race, insisting that Chelsea's only hope of silverware this season was in the Champions League.

But striker Kalou thinks otherwise. He said: "We have to fight for both competitions, even though, in the Premier League it will be more difficult to win it."

Kalou added: "But we have to do like we did on Tuesday night, we have to keep believing and take it game by game. I think we are showing the good side of Chelsea, because we can't just fight for one competition, we always fight for every competition."

Kalou hopes that Chelsea's good record at Wembley will ensure that they lift the Champions League for the first time in their history if they make the final, which is being played at the home of English football on May 28.

Chelsea have not lost a cup final since Kalou joined the club in 2006 and he hopes that will be a good omen if they reach the final.

"I love playing at Wembley. It is a great stadium, it has an amazing atmosphere and it is a special place for us," Kalou said.

"Hopefully we can get here for the final because it is our lucky stadium. Every time I came to Wembley for a final, we have had a good game and we won."

Chelsea were boosted on Thursday by the news that Yossi Benayoun has returned to light training. The midfielder has been out since suffering a torn Achilles on his second start for the club in September but is expected to be back in action next month.

David Luiz, who scored Chelsea's first in Tuesday night's win, picked up a minor hamstring injury against United but is expected to figure in the Blues' next match against Blackpool on Monday night.
